About

Dental Smile Analyzer

Features
Read full description

Smile analysis for dental professionals Evaluate the esthetic harmony of the anterior teeth using just two photos: a smile photo and a cheek-retracted photo. With assessment criteria informed by published research, Dental Smile Analyzer helps you explain findings to patients, communicate treatment goals, and document cases. How It Works 1. Enter the clinical crown lengths of the right and left central incisors in millimeters to calibrate measurements in the photos. 2. Take or select a smile photo. 3. Take or select a cheek-retracted photo. 4. Follow the prompts to mark anatomical landmarks and view your results automatically. Features - Smile Harmony Score: Get an at-a-glance overview with a score from 0 to 100. - Detailed esthetic assessment: Review more than 30 parameters graded A–D, including incisal edge position, gingival margin levels, tooth angulation, tooth width ratios, dental midline, smile arc, tooth shade, and tooth brightness relative to skin tone. - Visual guides for patient communication: Highlight areas of concern with reference lines overlaid directly on the photos. - Ideal smile design: Overlay an idealized design of the six anterior teeth on the photo to help patients visualize treatment goals. Adjust tooth width, length, smile arc, and shade. - PDF reports: Bring clinical photos, assessment overlays, and the proposed smile design together in a single report. - Case records: Save cases by patient ID or name and revisit them at any time. - On-device privacy: All photos and patient data remain on your device. No data is uploaded.

Verdict

The call

The clearest difference is in-app purchases: 1D | 日本最大級の歯科医療メディア at none against Dental Smile Analyzer's 2. 1D | 日本最大級の歯科医療メディア also leads on iOS requirement (15.0 vs 17.0). Dental Smile Analyzer's advantage is update cadence (every 5 days vs every 3 weeks). On price, ads and device support there is nothing between them.
